What is the priority nursing assessment for a patient diagnosed with rheumatoid arthritis (RA) and Sjögren's syndrome?

Choice A reason: Oxygen saturation is important in general assessments but is not the primary concern in RA and Sjögren’s syndrome unless respiratory symptoms are present. Choice B reason: Abdominal assessment is not directly related to the complications of RA or Sjögren’s syndrome. Choice C reason: Sjögren’s syndrome primarily affects moisture-producing glands, leading to dry eyes and potential corneal damage. Visual assessment is critical to prevent complications such as keratitis or corneal ulceration. Choice D reason: Breath sounds are relevant if there is suspicion of pulmonary involvement, but visual assessment takes priority in this context due to the direct impact of Sjögren’s syndrome on ocular health.
